Kazan Optical-Mechanical Plant

KOMZ was established on 8 February 1940, primarily to manufacture binoculars, artillery scopes, and tank sights for the Red Army. Most of the plant's engineers and production staff were transferred from the State Optical-Mechanical Plant in Leningrad (known as GOMZ and later as LOMO). By the end of World War II, KOMZ had produced 700,000 scopes and pairs of binoculars for the Soviet war effort. In the postwar era, KOMZ also manufactured a number of products for the commercial market, namely film cameras.

During the late 1980s, KOMZ greatly diversified its product range and also began to manufacture laser rangefinders, depth gauges, laser spectrometers, and medical instruments.
